Why does literary fiction hate genre?

Literary fiction is an artificial luxury brand but it doesn’t sell. So nobody benefits by fencing it off from more popular writing.

It’s always a problem when one of literature’s big beasts wanders off the reservation into the badlands of genre. The latest to blunder through the electric barriers erected around the safe zone is two-time Booker prize nominee David Mitchell, whose new book Slade House is undeniably a haunted house story. Or, as the Chicago Tribune put it, his “take on a classic ghost story”. As if the thousands of genre ghost stories written every year by horror writers weren’t also one individual’s take on that classic form.
